Research and Application of Medium-frequency Brazing of Cu-W Contact
Contact component which is made of red copper and CuW70
plays an important role in switchgear applications.It withstands high temperature
high voltage
wear resistance and certain strength.The quality of products is directly determined by the welding state.In the past
our company used flame brazing in contact welding
low efficiency
low passing rate
seriously restricted the production.In order to settling this problem
we demonstrates that medium-frequency induction heating with high efficiency is the most useful way for welding of contactors part because heating with high rate could reduce oxidization and increase hardness by experiment and discussion.
